IPC: G01C21/24
Filed: 1989-12-04
Abstract: PURPOSE:To improve the catching characteristic by switching and outputting an output of a pitching angle measuring circuit to the maximum in the range not smaller than a predetermined pitching angle by use of an output of an earth pulse discriminating circuit. CONSTITUTION:In this attitude angle measuring circuit, an earth pulse discriminating circuit 11 and a data switching device 14 are added to a pitching angle measuring circuit 12 and a rolling angle measuring circuit 12. A reference pulse C from an encoder circuit, an earth pulse E from an analog signal processing circuit, an encoder pulse ENC, and a timing signal P are outputted to the circuit 12 which in turn outputs a pitching angle. The output of the circuit 12 is switched by a switching device 14 according to a data control signal from the circuit 11. The circuit 13 outputs a rolling angle based on the earth pulses E1, E2 from north and south infrared detectors, pulse ENC, and signal P. Since the circuit 11 is additionally provided, the general measuring mode is distinguished from the other mode. Therefore, at the other operating ode than the general measuring mode, the polarity of the pitching angle at that time is detected, and the maximum value of the data of the pitching angle is outputted. Accordingly, the output transmitting characteristic is improved.

IPC: G01B11/10
Filed: 1993-12-16
Abstract: PURPOSE:To detect the abnormality of external size at high speed with high accuracy by monitoring the movement of a diffraction pattern due to the fluctuation of the external size of a specimen by a pair of photosensors. CONSTITUTION:When laser beams 31 are formed into a parallel luminous flux by a lens 32 and converged by a lens 33, the diffraction pattern 30 of a wire rod 2 as a specimen arranged between the two lenses 32, 33 is observed on a detecting surface 34, and the direction of the expansion of the pattern 30 crosses at a right angle with the direction of the extension of the wire rod 2. Two pairs of photosensors 41 consisting of photosensors 41a, 41b are arranged at places, where for example primary diffracted light in a specified order is received in the pattern 30 on a substrate 40 disposed on the detecting surface 34 at that time. Consequently, the sensors 41a, 41b mutually receive the primary diffracted light by the same quantity of light when the wire rod 2 has size in conformity with the stipulations. When the wire rod 2 has thicker (thinner) than the stipulations, light having the larger quantity of light is projected to the sensor 41a,(41b). Accordingly, the difference of the light-receiving signals of the sensors 41a, and 41b, is arithmetically operated, thus detecting the normality and abnormality of the external size of the wire rod 2.
